Benefits of technology

[0003]There are many encryption schemes, but the Advanced Encryption Standard (AES) is quickly being adopted as the industry standard.

Problems solved by technology

Once the moving is complete, it would then mark the current block as bad, thereby averting data loss.

example implementation

[0039]The product would be shipped as CD+Public, meaning the storage device, when connected to a PC, would provide a CD icon and a storage icon in the My Computer window, by pretending to the operating system of the host to be or to contain a CD drive. In the CD portion, there would be an application resident to make the device “Secured”. When launched, the program prompts the user for a password and then encrypts the secure partition with the master key and IV, as described above.

[0040]One method to generate a 32-bit random number in a USB storage system is to use the USB frame number (a random number that is generated by the USB host, such as a PC, every millisecond) and an internal counter in the controller that is incremented every system clock and that has a random starting value that cannot be predicted, as previously discussed in the description of FIG. 1.

[0041]FIG. 7 shows a block diagram of such an exemplary asynchronous random generator 700, using both a frame number 701 a...

Abstract

In one embodiment, method that can be performed on a system, is provided to security implementations for storage devices. In one embodiment, the method comprises providing a separate encryption seed for each of a plurality of separate addressable blocks of a non-volatile storage device, wherein a common encryption method is to encrypt data to be stored on the plurality of separate addressable blocks. In one embodiment, the storage device is a portable storage device. In one embodiment, encryption seed is an Initialization Vector (IV). In one embodiment, the encryption seeds comprise at least one of a media serial number and a logical block address corresponding to the respective block of the non-volatile storage device. In an alternative embodiment, the method further comprises storing at least a part of the separate encryption seed of the separate blocks of the non-volatile storage device within the respective blocks of the storage device.

Description

FIELD OF INVENTION[0001]This invention relates to security in portable digital devices such as flash memory cards or rotating magnetic disks.BACKGROUND OF THE INVENTION[0002]Portable digital storage devices are becoming increasing popular. These devices include solid-state storage such as flash memories and traditional hard disks. This popularity extends to the leading flash media, such as CompactFlash, Secure Digital Card, Memory Stick PRO, MultiMediaCard, Flash Drives, and their electrical variants. These devices can easily store gigabytes of data, weigh a few ounces, and be no bigger than a credit card. The problem with these devices is they are easily lost. Many people today carry large amounts of vital data on devices, which they keep in their pockets. It is very important that this data be encrypted to ensure that only the owner can read it.[0003]There are many encryption schemes, but the Advanced Encryption Standard (AES) is quickly being adopted as the industry standard.[000...
